Filters allow you to customize your view of the mempool to only see transactions that are interesting to you.
Go to Ethernow.xyz.
Login by either connecting your wallet or connecting with email. This will allow you to save your filters for future use.
Access the filter panel by clicking on the "Filters" button at the top right of Ethernow.
Once the panel is open you can apply a filter.
Click on a prefilled address set from the "Feature Addresses" section to quickly apply a filter.
Customize the attributes from scratch directly in the panel to build a custom filter.
Feel free to mix and match both approaches!
Click "Apply" at the bottom to view the result.
If you want to store the filter for future use, click "Save". Give the saved filter a name and a description.
To find your saved filters, navigate to the left hand sidebar and select "My Filters".
Share your saved filter by copying the URL.
Featured addresses are a quick way to filter for a group of addresses that you are interested in.
Clicking on an address group, such as "Uniswap", will select it. Clicking it again unselects it. Selecting multiple address groups will create an "OR" logic and surface matching results for all the selected addresses. Click "Apply" to view the results.
The following is a list of the Ethernow featured addresses and the addresses they are filtering for:
If you would like to have your protocol featured on the featured list please reach out.
The following is the definition
Grouping of addresses.
Transactions that did not go through the public mempool.
Sender or Recipient address (wallet or contract, generally).
Includes : default, filters for the address anywhere in the payload, including the to/from, internal transactions, net balance changes and logs
To : filters only on the "to" field in the payload
From : filters only on the "from" field in the payload
4-Byte signatures are functions identifiers (contract methodName).
Event signature (hex) are event identifiers (log topic0).
Status of this transaction: success / failed.
Denotes the gas pricing used for this transaction.
type: 0 represents legacy transactions (pre-EIP-1559).
type: 1 represents EIP-2930 transactions that include an access list.
type: 2 are EIP-1559 transactions.
type: 3 are EIP-4844 transactions.
Amount of ETH transferred directly from the "from" address, in wei.
Maximum number of units of gas that the sender allows for this transaction.
The price per unit of gas, in gwei.
Private transactions are defined as transactions that are never seen by Blocknative nodes in the mempool before landing on-chain. When checked, the Ethernow view will be filtered to only display private transactions.
Once selected, Ethernow will show you all matching blocks containing private transactions on the left column.
When "Private Transactions Only" is checked, the public mempool live feed will be empty.
This field allows you to filter by address. All addresses will be applied using an "OR" statement. The more addresses added, the wider the set of results will be.
When using the Includes filter, the filter applies to the entire payload, including the to/from, internal transactions, net balance changes and logs.
When using the To filter, the filter applies to the "To" address in the payload.
When using the From filter, the filter applies to the "From" address in the payload.
4-Byte signatures are widely used in smart contracts to uniquely identify functions. It helps determine which function is being called when a transaction interacts with a smart contract.
Using this field you can filter by 4-Byte signature which is a unique ID derived from the first four bytes of a function's signature hash. Each signature applied will use an "OR" statement. The more signatures added, the wider the set of results will be.
For example, the 4-Bytes 0xa9059cbb will show transfer transactions while 0x022c0d9f will show you swaps.

Using this field you can filter by event signature which is a unique identifier generated from an event's name and parameters. Dapps will listen for specific events emitted by smart contracts to react to changes or triggers within the blockchain ecosystem.
Each signature applied will use an "OR" statement. The more signatures added, the wider the set of results will be.
For example, the hex signature 0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef will show you transfer log events:

Using this field you can filter for transactions that have either succeeded or failed to get on chain.
All boxes will be applied using an "OR" statement. The more boxe you check, the wider the set of results will be.
If all boxes are left unchecked, you will get the full set of transactions.
Using this field you can filter for the type of gas used for a transaction.
Type 0: represents a legacy transaction, they use traditional gasPrice (pre-EIP-1559).
Type 1: represents a legacy transaction with the addition of access_list (pre-EIP-1559).
Type 2: this type was introduced by EIP-1559 and adds maxPriorityFeePerGas and maxFeePerGas to specify the transaction fee. Most Ethereum transaction use Type 2.
Each type applied will use an "OR" statement. The more types applied, the wider the set of results will be.
This represents the amount of ETH transferred directly from the "from" address.
You can define a range by specifying: a min value, a max value, or both for a custom range.
Value here is denominated in WEI.
This represents the maximum number of units of gas that the sender allows for this transaction.
You can define a range by specifying: a min value, a max value, or both for a custom range.
Gas here is in denominated in GAS UNIT.
This represents the price per unit of gas.
You can define a range by specifying: a min value, a max value, or both for a custom range.
Gas Price here is in denominated in GWEI.
Login via wallet or email (magic link) to save a filter or view your saved filters.
Click on the "Save" button.
Fill in the name and description and then save your filter.
Retrieve your saved filter by clicking in the left navigation menu on "My Filters".
Sharing a filter allows anyone to see the Mempool view you constructed. You can share a saved filter two ways:
Go to "My Filters" on the left hand navigation menu and click the copy icon to save to clipboard and share on a platform of choice.
When your filter is open on the Ethernow view, click on the share button that is at the top of the Filter Panel.
